Abstract

The invention discloses a connecting method and device of silicon cores, and relates to the field of polycrystalline silicon. In order to solve the problem of low production and preparation efficiencyof single welding of single silicon core, the technical scheme is provided: the connecting method comprises the following steps: clamping components of multiple silicon cores are arranged, to-be-connected silicon cores are fixed in clamping components, a control system regulates a heating system to heat and cool ends of the to-be-connected silicon cores to connect the multiple silicon cores, after the connection, the control system automatically takes out the silicon cores from the heating system, and the purpose of connecting multiple silicon cores synchronously is achieved.

Description

technical field [0001] The invention relates to the field of polysilicon production equipment, more specifically, it relates to a method for connecting silicon cores and a device thereof. Background technique [0002] The mainstream polysilicon material manufacturers in the market use the improved Siemens method to produce polysilicon. Polysilicon is prepared by reactive deposition of silicon-containing gas on the surface of a polysilicon carrier in a reduction furnace. The polysilicon carrier is the silicon core, which is evenly distributed on the chassis of the reduction furnace through the clamping device. The two silicon cores form a conductive circuit through the beam structure on the top. Many pairs of silicon cores conduct electricity through the electrodes of the chassis and heat up to the gas reaction temperature. The silicon-containing gas is reduced and deposited on the surface of the carrier, and the silicon core grows to form a silicon rod along with the deposi...
